JDBC in Web Service Glassfish

I have made an application with the java JDBC driver for MYSQL and that works fine. But now I'm trying to implement a web service into my ap开发者_如何学运维plication and I can't seem to get a connection made. Do I need to use a different driver or different way to connect to the MySQL server?

Thanks

You can use the same driver. Most likely you don't have your connection pool in Glassfish properly set up.

You can read about it here http://docs.sun.com/app/docs/doc/820-7692/ablih?l=en&a=view

You have to put the JDBC driver JAR either in a /lib directory that's visible to Glassfish (if it's shared) or in the WEB-INF/lib of your web service WAR.

You don't say what the error was. If it's a ClassNotFoundException, it means the class loader couldn't find the JDBC driver JAR.

If the error message is "no suitable driver found", it usually means that the syntax of your connection URL isn't correct for the given driver. The good news in that case is that the driver .class was picked up by the class loader.

Were you going to create a connection with a DriverManager, like you probably did with your app, or were you going to be ambitious and try to set up a connection pool?
